Allow ChainRouter::match() to use the correct exception message when a RequestMatcherInterface router is used.

Currently, even if doMatch() is called via match(), as long as the router cares for a request, it will create one and the exception handling will not use the path-specific message, it will use the request-based message.
Well, it depends. Are we more likely to have 0 routers that implement RequestMatcherInterface, or more likely to have >1 routers that implement RequestMatcherInterface?
Because right now, we optimize for 0. If we move that code outside the foreach and no routers need the created request when called from match(), that'd be an extra Request::create() call.
